Karl Fischer Titration System
Accurate. Rapid. Reliable. Precise Moisture Analysis. Built for Excellence.
Karl Fischer titration is an accurate, rapid and efficient method for determining the water content in samples. When the sample is titrated in the presence of SO₃, I₂, and an organic base, moisture from the sample extracted in the solvent, can be quantitatively estimated. Dry methanol is used as a solvent in Karl Fischer titration.
Our goal is to deliver analytical instruments that provide true end-point accuracy, chemically inert & leak-proof fluid systems, GLP and 21 CFR Part 11 compliance, and dependable performance for critical industries.
How It Works
Engineered with precise endpoint detection, hermetically sealed vessels, automated reagent addition, and continuous moisture leak monitoring.
- Indicator-electrode (two-pin platinum) with constant polarizing current for precise endpoint detection.
- Low solvent requirement with specially designed hermetically sealed vessel.
- Calculated doses of Karl Fischer reagent added automatically as per selected stop criteria.
- Background signal correction through offset mode.
- Built-in reagent standardization by Water or Sodium Tartrate for titre factor/concentration (F).
- Teflon-based liquid handling path (tubing, valve & syringe with teflon plunger) ensures chemically inert and leak-proof system.
- Magnetic, adjustable-speed stirrer for efficient moisture extraction.
- Continuous monitoring and automatic neutralization of moisture leak in the vessel.
- Results including leak rate are displayed on backlit LCD and printed in a tabulated form.
Minimum Dose Mode
The titration is stopped when the mV does not rise above the stop band in specified delay time.
Drift Mode
The titration is stopped if the calculated drift value is less than or equal to entered drift value in µl/min.
